Inherit `value-of` class constant (static behavior)

[distantnative]

How could I realize the follow (if at all)?

Where in class B the template T would be of BItem as declared by the ITEM_CLASS const?

I found these snippets:

<?php

class Item {}
class BItem extends Item {}

/**
 * @template T
 */
class Base {
	
}

/**
 * @extends Base<value-of<self::ITEM_CLASS>>
 */
class A extends Base {
	public const ITEM_CLASS = Item::class;
}

/**
 * @extends A
 */
class B extends A {
    public const ITEM_CLASS = BItem::class;
}

Psalm output (using commit ef3b018):
